Reviewed by Calculator Editorial Team

Thithi (also called Tithi) is a lunar day in the Hindu calendar system. It's one of the six main components of the traditional Hindu calendar, along with Vara (day of the week), Nakshatra (lunar mansion), Yoga, Karana, and Ritu (season). Thithi dates are crucial for determining auspicious times for religious ceremonies, festivals, and daily activities in Hinduism.

What is Thithi?

The word "Thithi" comes from the Sanskrit word "Tithi," which means "day" or "time." In the Hindu calendar, a Thithi is a lunar day that lasts approximately 24 hours. The lunar month is divided into 30 Thithis, with each Thithi corresponding to a specific day in the lunar cycle.

Thithi dates are calculated based on the moon's position relative to the sun. The first day of the lunar month is called Pratipada, and the last day is called Amavasya (new moon) or Purnima (full moon).

Types of Thithis

There are three main types of Thithis:

  1. Shukla Paksha: The waxing phase of the moon, from New Moon to Full Moon.
  2. Krishna Paksha: The waning phase of the moon, from Full Moon to New Moon.
  3. Amavasya: The day of New Moon, when the moon is not visible.

Importance of Thithi

Thithi dates are essential for determining auspicious times for religious rituals, festivals, and daily activities in Hinduism. Many Hindu festivals and ceremonies are scheduled based on specific Thithis. For example:

  • Diwali is celebrated on the Amavasya (New Moon) of the Kartika month.
  • Holi is celebrated on the Purnima (Full Moon) of the Phalguna month.
  • Navratri is celebrated over nine days, with each day corresponding to a specific Thithi.
